Data Sheet

Cisco Unified CallManager Version 4.2

The Cisco

Unified Communications system of voice and IP communications products and applications enables

organizations to communicate more effectively—helping them to streamline business processes, reach the right

resource the first time, and impact the top and bottom line. The Cisco Unified Communications portfolio is a key part

of the Cisco Business Communications Solution—an integrated solution for organizations of all sizes which also

includes network infrastructure, security, and network management products, wireless connectivity, and a lifecycle

services approach, along with flexible deployment and outsourced management options, end-user and partner

financing packages, and third-party communications applications.

Cisco Unified CallManager is the call-processing component of the Cisco Unified Communications System. Cisco Unified CallManager

extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices,

voice-over-IP (VoIP) gateways, and multimedia applications. Additional services such as unified messaging, multimedia conferencing,

collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco Unified

CallManager APIs. Cisco Unified CallManager is installed on Cisco Media Convergence Server (MCS) 7800 Series of server platforms

and selected third-party servers. It has a suite of integrated voice applications and utilities, including the Cisco Unified CallManager

Attendant Console—a ad-hoc conferencing application, the Cisco Unified CallManager Bulk Administration Tool (BAT), the Cisco

Unified CallManager CDR (call detail record) Analysis and Reporting tool the Cisco Unified CallManager Real-Time Monitoring Tool

(RTMT), the Cisco Unified CallManager Auto-Attendant (CM-AA), the Tool for Auto-Registered Phone Support (TAPS), and the Cisco

Unified CallManager Assistant application.

FEATURES AND BENEFITS

Cisco Unified CallManager Version 4.2 is an enterprise IP telephony call-processing solution that is scalable, distributable, and highly

available. Multiple Cisco Unified CallManager servers are clustered and managed as a single entity. Cisco Unified CallManager clustering

yields scalability of from 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking multiple

clusters allows system capacity to reach 1 million users in a system of more than 100 sites. Clustering aggregates the power of multiple,

distributed Cisco Unified CallManager installations, enhancing the scalability and accessibility of the servers to phones, gateways, and

applications, and triple call-processing server redundancy improves overall system availability.

Call Admission Control (CAC) helps ensure that voice quality of service (QoS) is maintained across constricted WAN links, and

automatically diverts calls to alternate public switched telephone network (PSTN) routes when WAN bandwidth is not available. With

Cisco Unified CallManager Version 4.2, devices can automatically update location information as they move from location to location to

improve CAC and emergency service performance.

The enhancements provided by Cisco Unified CallManager Version 4.2 offer improved security, supportability, manageability, as well as

usability enhancements to user features, including Park, Hunt Group, Cisco Unified CallManager Assistant, and Call Pickup features that

have been supported in past releases.

The Call Park feature now allows users to park a call to a specific park slot. Users now also can have a busy-lamp-field (BLF) and speed-

dial button that tells them whether or not the park slot is available. The feature is easily invoked by performing a transfer to the park slot.
